Question

1.In a nationwide survey of n = 500 adults, the sample proportion who answered yes to the question “During the last year did anyone break into or somehow illegally get into your home or apartment?” was .06 (or 6%). Suppose the FBI set of goal of 10% for break-ins, and they want to see if the current data show they are below that mark. The test statistic for this problem is -2.98. What is the p-value for this tests statistic? (use 4 decimal places)?

An import threshold for mercury in crayfish is 9 parts per billion (ppb). A study obtained a random sample of 120 crayfish from a large lake. Of these, 24 have levels of mercury that exceeded 9 ppb. Past research had shown that 25% of the crayfish had levels that exceed 9 ppb. The researchers wanted to see if there was a change in contamination in crayfish. The test statistic for this problem is -1.26. What is the p-value for this tests statistic? (use 4 decimal places)?
